Female judge calls defendant "a bit of a c*nt" - presumably this is a legal first?

This is from the Legal Cheek website:

Judge Patricia Lynch QC made her shocking comment while sentencing 50-year-old John Hennigan for breaching his anti-social behaviour order (ASBO).

Mid way through Lynch’s sentencing remarks, Hennigan — who has 23 convictions to his name — told her she was “a bit of a c**t”.

Without missing a beat, Lynch, who became a circuit judge in 2014, responded:

"You are a bit of a c*** yourself. Being offensive to me doesn’t help..."

...Hennigan then responded:

"Go f*** yourself."

Remaining cool, calm and collected, Lynch, who is a former member of London’s Red Lion Chambers, retorted:

"You too."

According to the account of the charming offender's court appearance in The Sun:

Hennigan then banged on the glass panel of the dock at Chelmsford Crown Court, performed a Nazi salute and twice shouted “Sieg Heil” before starting to sing “Jews gas them all….”

Judge Lynch, still speaking in a measured tone, commented: “We are all really impressed. Take him down.”

When I was a lad, judges used to halt proceedings to ask questions like "And what, precisely, is the meaning of the term Daddy-oh?", and now (to borrow a phrase of Harry Redknapp's to describe soccer supporters indicating disdain for certain players during a match) they're merrily "c*nting off" defendants. How times have changed! And yet it's hard to feel too censorious regarding M'lud's behaviour (or should that be M'lady?).
